# OPA Wasm and WASI experiment

## What?

This is the scratchpad for rewrapping OPA's wasm modules into a format that can

be run with a plain WASI host.

## How?

Requirements:

- `export-audit` and `wasmlink` from https://github.com/fixpointOS/wasm-tools/

- [zig](https://ziglang.org/)

`run.sh` contains a set of steps that lead to a successful call of `wasmtime output.wasm`.

The policy.wasm has to be supplied out of band, there's no example here (yet).

The one I had used was

```rego

package play

allow := { "one": 1 }

```

- compiled to wasm via `opa build -t wasm x.rego -e play/allow`

- extracted via `tar zxvf bundle.tar.gz /policy.wasm`
